I’ve set up emacs to display line numbers (global-linum-mode 1), and it works until I start enlarging the text via text-scale-adjust
The line numbers column starts to shrink, and disappears entirely after a few increments.
When it has fully disappeared, further increments have no more effect on the left edge.
Is this a know issue? Is there a workaround?
Using GNU Emacs 23.1.1 in Ubuntu 10.04.

Method 1
Here is a workaround. It works on my emacs 23.1.1. This same question came up again (months later), and I’d learnt a bit about elisp in the mean time, so I had a go at it. See the following link for my answer there. Font size issues with Emacs in linum-mode.
Method 2
The easiest, most straightforward solution I’ve seen just to set the line numbers to a fixed height. This can be accomplished easily, in accordance with user78810‘s answer: Font size issues with Emacs in linum-mode
To wit, add the following line in your emacs config (or to your dotspacemacs/user-config function, if you’re spacing out evil style):
(eval-after-load "linum" '(set-face-attribute 'linum nil :height 100))
Method 3
Here’s my solution. May want to change line-number face which used for display-line-numbers-mode to linum.
(defun post-text-scale-callback ()
;; fix line number text size
(let (new-size)
(floor (* (face-attribute 'default :height)
(expt text-scale-mode-step text-scale-mode-amount))))
(set-face-attribute 'line-number nil :height (new-size))
(set-face-attribute 'line-number-current-line nil :height (new-size)))
(add-hook 'text-scale-mode-hook 'post-text-scale-callback)
